The interrupting curve drops to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — so the SCCR headroom is strongest on 240 V and 480 V distribution, but you lose a lot of that margin above 500 V. ## Ratings that drive the fit That 110 A drop means the breaker's real-world capacity in a warm panel is 520 A — size the upstream transformer and busbar accordingly. That depth (110 mm) is the dimension from the mounting surface to the front of the breaker — important for shallow backpanel clearance. The 138 mm width per 3-pole unit is standard for this frame class, so it fits existing SENTRON 3VA panel layouts without re-drilling. The 3VA frame accepts plug-in or fixed connections; this order code ships with the undervoltage release pre-installed. The auxiliary switch block (2 aux + 1 trip alarm) is factory-configured — no field assembly required. For a retrofit into an existing SENTRON lineup, the 138 mm width per pole matches the 3VA family footprint, so busbar alignment holds.","metaTitle":"Siemens SENTRON 3VA2463-6HN32-0CH0 MCCB, 630A, 242kA","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0CH0 molded case circuit breaker, 630A at 40°C, 3-pole, 242kA interrupting at 240V.
